  • Patent number: 10032270
    Abstract: A system and methods for detecting particles and soluble chemical entities in body fluids consists of a system consisting of a microscopic apparatus, a sample chamber and reagents and methods used to detect, classify and enumerate particles and chemical entities in body fluids. Body fluids containing particles combined with reagents sediment to the bottom of a viewing chamber bringing them into the focal place of a digital microscopic detector. Particles identified as areas within a captured digital image that absorb or emit electromagnetic radiation can be further classified based on additional absorbed or emitted electromagnetic radiation within the predefined areas of the first digital image. Soluble chemical entities in body fluids are detected and concentrations determined using transmitted or emitted electromagnetic radiation using known chemical or antibody reactions, making the microscopic device a general purpose detector for in vitro determinations using body fluids.

    Abstract: Methods, systems and apparatus that provide for perceptual, cognitive, and motor behaviors in an integrated system implemented using neural architectures. Components of the system communicate using artificial neurons that implement neural networks.

  • Patent number: 9370336
    Abstract: A model-based method for assessing acoustic signal quality in a heart monitoring device. The personal heart sound interval distribution of a person being actively monitored is compared with a modeled global heart sound interval distribution shared by most human beings after which processing action is taken consistent with the quality assessment. The error in the best fit between the personal interval distribution and the global interval distribution is presumed to be caused predominantly by noise, allowing the quality of the fit to serve as a proxy for the level of noise in the acoustic signal and used in making processing decisions.

  • Patent number: 7853323
    Abstract: In general, the invention is directed to a technique for selection of parameter configurations for a neurostimulator using neural networks. The technique may be employed by a programming device to allow a clinician to select parameter configurations, and then program an implantable neurostimulator to deliver therapy using the selected parameter configurations. The parameter configurations may include one or more of a variety of parameters, such as electrode configurations defining electrode combinations and polarities for an electrode set implanted in a patient. The electrode set may be carried by one or more implanted leads that are electrically coupled to the neurostimulator. In operation, the programming device executes a parameter configuration search algorithm to guide the clinician in the selection of parameter configurations. The search algorithm relies on a neural network that identifies potential optimum parameter configurations.

  • Patent number: 7853089
    Abstract: An automated method for analyzing whether all cancerous or abnormal tissue has been removed as a result of surgical resection is disclosed. A number of tissue section slides are prepared representing all or a relatively large percentage of the tissue sample, and high-resolution digital microscopic images are formed of the sections. A clustering algorithm forms an image showing the healthy tissue margins, such representation being stored in a file of significantly smaller size than the original photograph. These two-dimensional image files may be formed into a three-dimensional image of the entire resected tissue, thereby improving the accuracy and ease by which a pathologist may determine if further surgery or radiation therapy, for example, are indicated.

  • Patent number: 7708700
    Abstract: A method of training a subject to improve anticipatory timing includes presenting the subject with multiple sequences of stimuli, receiving sensor signals associated with responses by the subject to the stimuli, and recording response times in accordance with the sensor signals, wherein the recorded response times are associated with the responses by the subject to the multiple sequences of stimuli, and wherein the response times have an associated distribution. The method further includes analyzing the distribution of response times for the subject to determine variability in anticipatory timing of the subject with respect to the stimuli, and generating a subject feedback signal corresponding to a result of the analyzing so as to train the subject to improve anticipatory timing of the subject. Also disclosed is a system for performing the aforementioned training method.

  • Patent number: 7676076
    Abstract: Image processing method for a digital medical examination image, the pixels of which are assigned a gray-scale value in each instance, with a minimum and a maximum gray-scale value being defined as limit values for the purpose of displaying the examination image, with the pixels being subjected to an evaluation by means of a neural network, in order to determine such pixels and to disregard them when defining the gray-scale values which are located in a direct radiation region or in a projected collimator region.

  • Patent number: 7306560
    Abstract: A system and method for providing computerized, knowledge-based medical diagnostic and treatment advice. The medical advice is provided to the general public over networks, such as a telephone network or a computer network. The invention also includes a stand-alone embodiment that may utilize occasional connectivity to a central computer by use of a network, such as the Internet. New authoring languages, interactive voice response and speech recognition are used to enable expert and general practitioner knowledge to be encoded for access by the public. “Meta” functions for time-density analysis of a number of factors regarding the number of medical complaints per unit of time are an integral part of the system. A re-enter feature monitors the user's changing condition over time. A symptom severity analysis helps to respond to the changing conditions. System sensitivity factors may be changed at a global level or other levels to adjust the system advice as necessary.

  • Patent number: 7297129
    Abstract: An object of invention is to display necessary information on a screen and display predicted information obtained by predicting the progression of the necessary information. In a bed-side information system, a body information monitor 11 measures arterial blood pressures of a patient 14. The body information monitor 11 measures systolic arterial blood pressures and diastolic arterial blood pressures, and calculates average values thereof. A Hematocrit monitor 12 calculates Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation. The body information monitor 11 transmits arterial blood pressure information to a desktop PC 15 and the Hematocrit monitor 12 transmits Hematocrit, change blood volume rate, and Venous Blood Oxygen Saturation to the desktop PC 15. The desktop PC 15 displays arterial blood pressure, Hematocrit, change blood volume rate, and Plasma Refilling Rate on a screen of a display using these information items.

  • Patent number: 7297108
    Abstract: A system and method for allowing a patient to access an automated process for managing a specified health problem called a disease. The system performs disease management in a fully automated manner, using periodic interactive dialogs with the patient to obtain health state measurements from the patient, to evaluate and assess the progress of the patient's disease, to review and adjust therapy to optimal levels, and to give the patient medical advice for administering treatment and handling symptom flare-ups and acute episodes of the disease. The medical records are updated, the progression of the disease is stored and tracked, and the patient's preferences for treatment are stored and then used to offer medical advice based on the current state of the disease. A prestored general disease trend curve is compared against a patient specific disease trend curve, and the system makes an automated response such as adjusting therapy.
